Construction method for composite grouting waterproof curtain
The invention relates to a construction method for a composite grouting waterproof curtain. The construction method includes the steps that periphery compaction grouting is constructed along the edge of a construction area to form a periphery compaction grouting curtain arranged on the edge of the construction area in a closed manner, and the periphery compaction grouting curtain goes deep into the bottom of a backfill layer; inner circumference compaction grouting is conducted in the construction area to form a closed inner circumference compaction grouting curtain, the inner circumference compaction grouting curtain goes deep into the bottom of the backfill layer, and a reserved space is arranged between the periphery compaction grouting curtain and the inner circumference compaction grouting curtain; and high-pressure jet grouting piles are constructed in the reserved space, wherein every two adjacent high-pressure jet grouting piles are meshed with each other. Compaction grouting is conducted on the two sides of preset positions of the high-pressure jet grouting piles through cement mortar, the high-pressure jet grouting piles are constructed after the cement mortar is solidified, the continuous and compact waterproof curtain is formed, the water prevention effect of the curtain is good, the construction speed is high, and cost is low.
